What is a User Agent?

A user agent is a string of characters that identifies the browser and operating system being used to access a website. This information is sent to the server with every request.

How to Find Your User Agent?

1. Open your web browser (Chrome, Firefox, Safari, etc.)
2. Visit a website like whatmyua.com
3. Your user agent will be displayed, including browser, OS, and device info.

Why is User Agent Information Important?

It helps developers optimize websites for different browsers and devices, ensuring compatibility and a better user experience.
